+

+ —
Addition operator

Description

Arithmetic operators perform operations of change-sign (negate), do-no-change-sign, logical AND logical OR, add, subtract, multiply and divide. Note that a value or an expression may fall between two of these operators, either of which could take it as its left or right argument, as in

a + b * c.

In such cases three rules apply:

1. * and / bind to their neighbors more strongly than + and −. Thus the above expression is taken as

a + (b * c)

with * taking b and c and then + taking a and b * c.

2. + and −
bind more strongly than &&, which in turn is stronger
than ||:

a && b - c || d

is taken as

(a && (b - c)) || d

3. When both operators bind equally strongly, the operations are done left to right:

a - b - c

is taken as

(a - b) - c

Parentheses may be used as above to force particular groupings.

Syntax

+a (no rate restriction)

a + b (no rate restriction)

where the arguments a and b may be further expressions.

Arguments

The arguments of + can be scalar values or k-rate one
dimensional arrays (vectors), or any combination. If one of the
arguments is an array, so is the value.
